hey great work there. I noticed that webkit is missing there. Maybe in the application framework layer? and another thing is the KeyguardViewManager which should be in the UI Framework/Application Framework layer.

Great idea!
The diagram is pretty messy though. I would start by making a vector image to allow zoom without loosing quality. It would also be nice if the colors of the “reference call” and “inheritance” diagram would be slightly different, not just black and bold black.
Anyway, great job!
